Closed-loop therapy adjustment
First Claim
1. A method comprising:
- receiving a therapy adjustment from a user, wherein the therapy adjustment received from the user comprises an adjustment of a value of at least one parameter of a therapy delivered to a patient by a medical device;
determining a value of a patient parameter in response to the receipt of the therapy adjustment from the user, wherein the patient parameter is sensed via a sensor and is indicative of at least one of patient posture or patient activity;
updating a table in response to the receipt of the therapy adjustment, the table comprising a plurality of records stored in a data structure, each record of the plurality comprising at least one value of the patient parameter and associated therapy information, the therapy information including the at least one parameter, wherein updating the table comprises associating the value of the patient parameter with the value of the at least one parameter; and
delivering the therapy to the patient via the medical device, wherein the therapy is delivered according to a respective record of the plurality of records that is associated with a currently sensed value of the patient parameter, wherein receiving, determining, updating, and delivering are performed using one or more processors.

Abstract
Techniques for detecting a value of a sensed patient parameter, and automatically delivering therapy to a patient according to therapy information previously associated with the detected value, are described. In exemplary embodiments, a medical device receives a therapy adjustment from the patient. In response to the adjustment, the medical device associates a sensed value of a patient parameter with therapy information determined based on the adjustment. Whenever the parameter value is subsequently detected, the medical device delivers therapy according to the associated therapy information. In this manner, the medical device may “learn” to automatically adjust therapy in the manner desired by the patient as the sensed parameter of the patient changes. Exemplary patient parameters that may be sensed for performance of the described techniques include posture, activity, heart rate, electromyography (EMG), an electroencephalogram (EEG), an electrocardiogram (ECG), temperature, respiration rate, and pH.

11. A system comprising:
-
a medical device configured to deliver therapy to a patient; a sensor configured to sense a patient parameter, wherein the patient parameter is indicative of at least one of patient posture or patient activity; and at least one processor configured to; receive a therapy adjustment from a user, wherein the therapy adjustment received from the user comprises an adjustment of a value of at least one parameter of a therapy delivered to a patient by a medical device; determine a value of the patient parameter sensed via the sensor in response to the receipt of the therapy adjustment from the user; update a table in response to the receipt of the therapy adjustment, the table comprising a plurality of records stored in a data structure, each record of the plurality comprising at least one value of the patient parameter and associated therapy information, the therapy information including the at least one parameter, wherein the processor updates the table by at least associating the value of the patient parameter with the value of the at least one parameter; and control the delivery of the therapy to the patient via the medical device, wherein the processor controls the delivery of therapy according to a respective record of the plurality of records that is associated with a currently sensed value of the patient parameter. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A system comprising:
-
means for receiving a therapy adjustment from a user, wherein the therapy adjustment received from the user comprises an adjustment of a value of at least one parameter of a therapy delivered to a patient by a medical device; means for determining a value of a patient parameter in response to the receipt of the therapy adjustment from the user, wherein the patient parameter is sensed via a sensor and is indicative of at least one of patient posture or patient activity; means for updating a table in response to the receipt of the therapy adjustment, the table comprising a plurality of records stored in a data structure, each record of the plurality comprising at least one value of the patient parameter and associated therapy information, the therapy information including the at least one parameter, wherein updating the table comprises associating the value of the patient parameter with the value of the at least one parameter; and means for delivering the therapy to the patient via the medical device, wherein the therapy is delivered according to a respective record of the plurality of records that is associated with a currently sensed value of the patient parameter.
